The digital data are intended for use by all government, academic, commercial, or other agencies in need of digital geologic map information.<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The bedrock geology was last mapped at a statewide scale 50 years ago at a scale of 1:250,000 (Doll and others, 1961). The 1961 map was compiled from 1:62,500-scale or smaller maps. The current map was created to integrate more detailed (1:12,000- to 1:24,000-scale) modern mapping with the theory of plate tectonics to provide a framework for geologic, tectonic, economic, hydrogeologic, and environmental characterization of the bedrock of Vermont.
